Question

Average cost of 5 apples and 4 mangoes is Rs. 36. The average cost of 7 apples and 8
mangoes is Rs. 48. Find the total cost of 24 apples and 24 mangoes.

Answer 1

Average cost of 5 apples and 4 mangoes = Rs. 36

Total cost = 36 × 9 = 324

Average cost of 7 apples and 8 mangoes = 48

Total cost = 48 × 15 = 720

Total cost of 12 apples and 12 mangoes = 324 + 720 = 1044

Therefore, cost of 24 apples and 24 mangoes = 1044 × 2 = 2088
